RTA’s PLUS series features medium-high power bipolar ministep drives. It is based on 5 families with different possibilities of command, interface and power input.All models are equipped with Chopper systems featuring high performance Mosfet power stages, microstepping up to 4.000 step/rev. and power input in AC (PLUS B, K, J, E, L) or DC (PLUS A). PLUS E and PLUS L series have to be used in coupling with EM series stepper motors from RTA, equipped with encoders that are able to detect loss of synchronism of the motors.
